Abstract

The utility model provides an electric welding tool, particularly a manual tin-feeding electric iron, which comprises a welding tube, a melting iron core, a handle and a connecting tube. The utility model is structurally characterized in that the center of a whole body which integrates the welding tube, the connecting tube and the handle is provided with a through hole which forms a passage for feeding tin wires. The purpose of feeding tin wires can be achieved by a pair of tin-conveying wheels on the handle being rotated by hand. An operator can heat the tin wires at any needed time, which realizes continuous weld. The utility model which has convenient use and low electricity consumption is an ideal welding tool for members of electrical appliances.

Description

Hand operated electric iron with tin feeding device

The utility model relates to a kind of electric welding instrument, is a kind of manual tin supplying electric iron specifically, is mainly used in the welding of electric elements.

The present widely used electric iron of people all is that scolding tin and electric iron are placed apart, has welding and is interrupted often the drawback that work efficiency is low.Existing a kind of novel electric iron need be with scolding tin in heat fused of melting chamber during use, and heat time heating time is long, and power consumption is big, and its controlling organization poor reliability, makes troubles to the user.

The purpose of this utility model is to overcome the deficiency of above-mentioned electric iron, and providing a kind of can place the tin silk in the electric iron, and the operator can realize continuous welding with using with the heating of tin silk, and power consumption is little, manual tin supplying electric iron easy to use.

The purpose of this utility model realizes by following case scheme: manually tin supplying electric iron comprises handle, the molten iron core, welded tube, welded tube connects with handle by connecting tube, the technical solution of the utility model is a welded tube, connecting tube, handle three center has a through hole, form the passage of supplying with the tin silk, handle has a cavity, two bearing pins are fixed with the through-bore axis vertical direction in the edge in this cavity, the a pair of toothed tin feeding wheel of tin silk feeding is installed in respectively on above-mentioned two bearing pins, one gap is arranged in the middle of two tin feeding wheels, interstitial site is relative with through-hole passage, and the soldering tip place of welded tube has one and tubaeformly goes out the tin hole.

Compared with prior art the utlity model has following advantage:

1, can realize continuous welding.This kind electric iron is provided with feed arrangement, and the tin silk is entered in the flatiron continuously, melts the tin silk incessantly, realizes the welding continuity.

2, power consumption is little, and is easy to use.This kind electric iron is with using with tin silk feeding heating, and heat time heating time is short, and the tin silk amount that residue has melted is few, and the singlehanded tin feeding wheel that rotates can be finished welding.

3, take scolding tin in the time of can preventing to weld the preheating weldment out of.This kind electric soldering iron tip has the tubaeform tin hole that goes out, thereby can prevent that the soldering tip vibration from flow out scolding tin.

Fig. 1 is a topology view of the present utility model.

Fig. 2 is along the cutaway view of A-A line among Fig. 1.

Fig. 3 is along the cutaway view of B-B line among Fig. 1.

The utility model is described in further detail below in conjunction with (accompanying drawing) embodiment:

With reference to Fig. 1, Fig. 2, Fig. 3, connecting tube 14 1 ends and handle 10 thread connection, the other end are inserted in welded tube 1 centre bore, constitute the electric iron main body, it is 3 millimeters through hole 11 that the three center has a diameter, this through hole forms the passage of supplying with the tin silk, and welded tube external part termination is a soldering tip, and above-mentioned through hole 11 diminishes at the soldering tip place, its diameter is 0.7 millimeter, take scolding tin when preventing to weld the preheating weldment out of, soldering tip has the tubaeform tin hole 17 that goes out, and makes tin stream rest on 16 places, variable cross-section position.Opposite side at soldering tip, half position of welded tube length is provided with the molten iron core, the molten iron core is by interior porcelain tube 6, external ceramic tube 4, resistance wire 5 is formed, the molten iron core retainer plate is on welded tube 1, the welded tube through hole position that it surrounds is a melting chamber, its outside asbestos 15 that add, scatter and disappear to reduce the resistance wire heat, porcelain ring 7 is enclosed within the connecting tube 14, be located between molten iron core and the handle 10, two pairs of posts 18 and 23 are arranged on it, in order to lead 19,20 and resistance wire 5 link, resistance wire 5 one ends are by binding post 18 and lead 20 UNICOMs, resistance wire 5 other ends enter fine porcelain pipe 24, by binding post 23 and lead 19 UNICOMs, the cannelure 8 that lead 19 is walked around the handle end face stretches out from wiring hole 21 with lead 20.Lead 19 and lead 20 is fixing at screw hole 22 places with screw.Outer cover 3 is covered on asbestos 15 and the porcelain ring 7, outer cover 3 centers are by welded tube 1, outer cover 3 is withstood the end face of handle 10 and lock by nut 2, welded tube 1 material is a red metal, connecting tube 14 materials are 30 steel, outer cover 3 is made for sheet metal, handle 10 adopts bakelite to make, its side has the convex epirelief of conveniently holding, and on the handle 10 except that having through hole 11, also has a wiring hole 21, one rectangular cavity 10a, cavity 10a is located at connecting tube 14 right-hand members, has a Baltimore groove support 13 in it, be welded with on the support 13 the parallel bearing

12 and 12 of two axis ', two tin feeding wheels 9 and 9 ' respectively that have a tooth be installed in this two bearing pins 12 and 12 ' on, and each tin feeding wheel can rotate around its bearing pin, support 13 is stamped to form by the steel plate of 1 millimeters thick, tin feeding wheel 9 and 9 ' make by shaped steel, and the tooth above it is stamped to form, there is a square hole at support 13 centers, this square hole is just in time withstood in connecting tube 14 terminations, makes support 13 keep stable in hollow cavity 10a, and there is a gap two tin feeding wheels 9 and 9 ' centre, gap value is 2.5 millimeters, and the present position, gap is relative with above-mentioned through hole 11.When using electric iron, with power connection, the tin silk is inserted through hole from tiller grip, rotate this to tin feeding wheel through tin feeding wheel 9 and 9 ' time with hand, make the tin silk enter melting chamber and fusing gradually, and the not fusing of the tin silk at tin feeding wheel place, when rotating tin feeding wheel, the teeth on the tin feeding wheel are bitten solder stick, make these the unfused scolding tin of preheating advance to melting chamber, so just the scolding tin that has melted in the melting chamber is extruded from the tin hole 17 that goes out of soldering tip, be welded in the joint of electric elements, reach the purpose of welding, scolding tin can constantly insert from tiller grip, rotate the continuity that tin feeding wheel 9 and 9 ' can realize welds, the tin feeding wheel that stops operating can stop to tell tin, stops welding, the utility model can singlehanded use, and also can resemble the common electrical flatiron scolding tin and electric iron use placed apart.
